JIGGING THE CANARD
..... Next, you will need to jig the canard cores on the jig table. It
would probably be a good idea to clean off the jig table of any bondo
chips, wood, epoxy, etc., so that you start with a clean surface.
..... Find the canard core female jigging templates (6)
..... Now study the sketches. The canard cores are jigged upside down on
the jigging table using the canard core female jigging templates. If
your table is not at least 200 inches long, you will have to extend it
like you did on jigging the main wing. As on the main wing, the shear
web is perpendicular to WLOO, and the canard core female jigging
templates have leading and trailing edges that are tangent,
respectively, with the leading edges of the canard, and the canard shear
web.
..... Begin by drawing a straight line along your jigging table and
marking the locations (BL's) of the canard core female jigging
templates. Next, temporarily set the canard core female jigging
templates on the jigging table .so that their trailing edges are the
distances from the straight line, called out in the accompanying
illustrations. Note that the outboard canard core female jigging
templates (the ones at BL100 right and BL100 left) are right on the
straight line. A string stretched spanwise with a weight attached at
either end may be helpful in establishing and keeping the straight line.
..... Now begin to trial fit the five canard cores into position. Be
careful in handling the foam cores to prevent damage to the foam. All
cores may have to be sanded in order to make them fit together within
the maximum tolerance of 1/16". The canard center section core is
already beveled to compensate for the anhedral angle, but it may still
have to be trimmed and sanded to obtain the fit on the joint within
1/16". The level lines on all cores must remain level at all times. This
is important, so take your time.
..... Stand back and sight spanwise along the canard to verify that the
canard is straight, and is not bowed or kinked. Verify that the leading
edges are straight, and that the trailing edges are straight also.
..... Don't be concerned if the canard core female jigging templates need
to be moved inboard or outboard to remove any bows or kinks. Also, a
long straight edge will help you looking for kinks and joggles, or dips.
..... When everything is perfect, mix up some bon do and carefully bondo
the canard core female jigging templates to the table top in the
necessary location. Next, rest the canard cores on the canard core
female jigging templates. Check the alignment and individual level lines
again; then again and again until every thing is Perfect, with a capital
P. The next step is to join the foam cores together with micro slurry
